vTo all 'whom it may concern: l

Be it known that I, Faun-:nica C. Scum- BER, a citizen of the United States. and

resident of New Douglas, Illinois, have in- -vented certain new and useful Improvements in 'Devices for Making Concrete ltoong-Tiles, of which the fol owing is a specification.

My invent: 'i relates to improved devices for making concrete rooting tiles, and has for its object to provide an apparatus in f which concrete may he received in' plastic condition and'formed in the desired contour to provide for lapping tiles adapted to enage with each other for the purpose of orming water-proof roofs.

In the drawings-Figure is a perspective view of a device embodying my invention in place upon a mixing table. Fig. 2 is a vertical view of the mold and its supporting frame in cross section, the trowel or Shaper being shown in place upon its hearings. Fig. 3 is a bottom plan view ot the trowel or Shaper employed in my in vention. tion of the mold employed in the illustrated form ot' my invention. Fig. 5 is a top plan view ot' the supporting trame. Fig. 6 is an elevation of the yoke whereby the parallel slidably mounted rods employed in the device of my invention are secured to each other. Fig. 7 is a ierspective view ot' the perforating pin employed in my inven` tion and carried by the yoke illustrated in Fig. t3. Fig. 8 is a transverse sectional view of the toothed collar by which the parallel slidably mounted rods are actuated. Fig. 5) is a vertical sectional view of the frame taken alon the line 9-9 of Fig. 5. Figa-1.() is a side elgevation of the frame.

As shown in the drawings, the device of my invention is adapted to be set upon the includes a frame having end walls 12-12 and sidewalls 13-13. The end walls 12-12 are provided near their bottoms with pairs ot' stationary lugs 14%14 in which one end of the links 1.5*15 is pivotally mounted by means ofthe pins 1G-18- A pair of mold-supporting bars l7-17 are vertically and slidably mounted above the lugs 14-14 and located against the end walls 12-12 and operatingfin the guides formed on the. side Walls 13-13 so as toretain the bars in position and guide the same during its vertical Fig. 4 is a longitudinal view in seemovement; the bars lT-l' having downwardly projecting portions 1T which operate in the guide-ways' on the side walls lil-dil. thel lower ends of said portion 1T contacting with the bottom ot' the trame so as to prevent;- said bars from being lowered farther than the position `shown by solid lines in Fig. t). The said bars 1T-1T heilig provided with projecting tongues 1S-1H to which the links 19--19 are pivotally secured by pins Q0. The links l.' -l5 are pro' vided at their inner extremities with tongues il (see Fig. 5) adapted to tit within the slots 22-22 withV which the inner ends of the links 15)-19 are provided. A second pair of links 22"?3 are provided atl their outer ends with yokes Bl--E-lwhich are connected to the ends ot' the links la7-45 and links 19--19 by pins i5- 2f to provide pivotal engagement. therewith. 'lhe links 23-22 have their opposite endsI in vertical alinement with each other and are respectively secured by means of the pins 2K3-2G to the upper and lower ends of the lever 2'( which is provided with a central opening 2T. a portion of said opening ot' largeI di-- ameter so as to permit the key 28 formed on the shaft 2H to move freely therein': "the reason ot' this is that, when the shaft 8 is operated by means of the handleQU, the shatt will partially rotate independent of the arm 2T until the kevcomes in contact with thel opposite edge ot' the larger portion ot`l the opening 2T', a further purposeot this operation being hereinafter fully set forth.

i ly means ot" the mechanism thus described the. hars 1T --IT are held normally at a point slightly below the level ot the tops ot.' theA end walls l2---l2 (see Fig. it) and when the handle Qi) is operated to throw the levers 27 into horizontal position the bars I7- v15T will. bethrown upwardly as indicated by dotted lines in Fig. t). llpon the outer upper snrfact. of the walls i2-12 are provided horizontal guides It-i`30. contoured on their upper faces to correspond with the shape, ot' and permitthe mold 31 to register with the said upper faces ot' said bars. When thel mold 31 isl placed in position upon said bars 17`17, said bars are lowered to the position illustrated in Fig. 9. Where the mold 31 vwill be. at a point beneath the level ot. the tops of the end Walls 12-12. The concrete mixture is then placed in plastic condition upon said The bars 1?17 are mold and heaped up until its upper surface is at all points in a plane above the level of the planes of the end walls 12-12 and side walls 13-13.

The mold 31 is provided with transverse grooves 32 having perforations 33 to receive a wire loop or the like, indicated by dotted lines 34 in Fig. 4, so that when -the concrete tile has been formed said inserted wire loop or the like will remain embedded in place therein While having free ends to admit of its being used as a securing means to hold the tile in place upon the roof.

The mold 31 is provided with a depression 35 having an opening 36, the object of said opening 36 being to permit the stylus 37 to be driven through said opening 36 and the tile molded around the same upon the mold 3l so as to form a hole for the reception of a securing means when the tile is to be set in position. This is accomplished at `the edge of thel tile; the stylus being made vertically adjustable by being mounted upon a block 38 having the slot 39. The bolt 40 passes through the slot 39, through the opening 41 in the yoke 42 to secure the stylus 37 to said yoke 42 in its proper adjusted position. The yoke 42 is provided with an opening 43- whereby the yoke 42 is mounted upon a sliding bar 44 and is secured in place thereon by means of the set screw 45. The yoke 42 has'at its lower extremity the opening 46 through which the short bar 47 passes, the yoke 42 being secured in place upon said short bar 47 by means of the set screw 48, and when properly secured both bars 44 and 47 are held rigid and in alinement with each other. The sliding bar 44 is provided with parallel pins 49-49 upon one of its sides. A collar 50 provided with a set screw 51 is mounted upon the shaft 28, the collar being provided with the tongue 52 whose outer end projects between and operates upon the pins 49449 to throw the bar 44 inwardly or outwardly with reference to the end walls 12-12, to place the stylus in position for forming the opening in the tile.

In operating the stylus, the handle 29 is first manipulated, turning the shaft; during this operation the tongue 52 operating against the pins 49 has a-tendency to manipulate the bars 44 thereby removing or replacing the stylus in its position, depending upon the manner in which the shaft is turned. For example, if the shaft is revolved in order to place the mold in an elevated position, as shown by dotted lines in Fig. 9, it is necessary first to withdraw the stylus from its position before the supporting bars together with the mold can be elevated, and this is accomplished by the turning of the shaft which will release the stylus and cause the arm 27 to remain stationary until the key 28 contacts with the opposite and to lower the mold to its normal position,

as Ishown by solid lines, a reverse movement is applied to the shaft and the arm and link members will remain inoperative until the vkey 28 on ythe shaft contacts with the opposite edge of the larger portion of t-he opening; and when said key contacts therewith, will again place the arm and links, together with the stylus, in the position as shown by solid lines.

To form the contour of the concrete tile or shingle 53, which is illustrated in section in Fig. 2, I provide ashaper or trowel 54 having at its terminals the handles 55, and upon its lower face is provided the transverse grooved bearing blocks 56-56 which have slidablc engagement with the tops of the hars or guides 30-30. The lower face of the Shaper is provided with grooves 57 to register with the general contourof the mold 31. The walls of said grooves 57 areat a slight angle to each other or, in other words, wedge-shaped, as illustrated 1n Flg. 3, so as to compress the concrete as the shaper 54 is drawn over the mold 31. Av

slab, shingle or tile of concrete thus having been formed, the Shaper 54 is removed andl whereupon a new mold is replaced and the process of forming the mold repeated. The guides 30-30 are made adjustableto regu:- late the thickness of the tile by being mounted upon supporting plates 58-58 having slots 59. through which bolts 6() pass to secure the supporting plates 5S upon the outer faces of the side walls 13.

By means of the described mechanism it is possible to form the concrete tile of any desired contour of uniform thickness quickly and accurately and with economy of ma'- terial, as the surplus concrete removed by the shaper 54 is cast upon the mixing table 11, and the durability of the device as a, whole is secured by the mechanical construction described herein, and in which no springs are employed.

The operation of my invention is as follows: To form a tile I first regulate the 0perating parts in position as' shown by solid lines in Fig. 9, and placing upon the upper surface of the supporting bars a mold-31 which is shaped to form the shape of the under side of the-tile. The shaft is operated so that Athe stylus 37 is in the position as shown in Fig. 5. The mixed concrete is then placed upon the mold between the walls of the frame and the operator then manipulates the shaper or trowel by pulling the same over the mold, said trowel being guided on the guides 30. The groove formed in the under side of the shaper or trowel is tapered or wedge-shaped, as previously described, and during the act of pulling the same over the mold, has a tendency to compress the material at the same time forming the outer contour or upper surface of the tile and after the tile is formulated by the shaper, an elongated projection 61 is formed of the material by means of the groove G2 formed in the Shaper and in the mold 81 is formed an elongated projection 63 which forms an elongated groove 64 in the finished tile, the same to correspond in size with the projection 61 so as to form a lock or lap joint when one tile is placed upon the other upon the roof, forming a leak-proof connection. After the material of the mold has been so formulated and sutliciently set, the

operator then, by the manipulation of theA handle Q9, turns the shaft Q8, causing the bar 44 to be operated and extract the stylus 37 from the material and mold, and by the continuation of the operation of the shaft, the arm 27 is operated and in turn manipulates the links, causing the same to assume the position shown by dotted lines in Fig. 9, raising the mold, together with its formed tile in a position so the operator can'remove the same to a convenient place for drying. After' the mold and tile has been removed, the operator places a new mold plate on the supporting bars, lowers the same by the reverse operation of the shaft and then the 4progress of forming another tile is repeated.
